A three-dimensional autonomous memristive chaotic circuit

Abstract

The invention provides a three-dimensional autonomous memresistive chaotic circuit, solving the problem that an existing third-order chaotic system cannot guarantee security in actual secure communication. The three-dimensional autonomous memresistive chaotic circuit comprises three circuit paths comprising a resistor, a capacitor, an operational amplifier, a multiplier and a sine module, whereinchaotic circuit characteristic equations of the three circuit paths comprise sin signals, the three circuit paths are built with elements, multiple uncertain attractors exist due to the periodicity ofa triangle function, the topological structure is more complex, the dynamical behaviors are sufficient, so that secure communication is harder to crack at a certain degree and is safer. The autonomous memresistive chaotic circuit is more innovative and special, ensures that secure communication is harder to crack, has a simpler structure, is easier to realize, and can conduct multiple, unique dynamical behaviors, thereby having application prospect and roles in fields like information processing and secure communication.
